THE ENGINE DIED ON ME IN A PARKING LOT AND WOULDN'T RESTART FOR ABOUT 15-20 MINUTES. THE SECOND INCIDENCE WAS THE SAME. THE THIRD INCIDENT, IT STOPPED ON ME AS I WAS COMING OFF AN EXIT TO GET ON THE HIGHWAY. I HAD JUST REACHED 50 MPH WHEN IT CUT OUT. IT WOULD NOT RESTART FOR 15-20 MINUTES. THE NEXT AND FINAL EVENT BEFORE REACHING A RESOLUTION TO THE PROBLEM...THE TRUCK CUT OUT AS I WAS ON AN EXTREMELY DANGEROUS AND BUSY SECTION OF HIGHWAY DOING 60 MPH. I THANK GOD IT WAS A STRAIGHT STRETCH OR SOMETHING FATAL COULD HAVE OCCURED. IN BETWEEN EACH OF THESE EVENTS, I TOOK THE TRUCK TO THE MECHANIC AND TRIED DIFFERENT OXYGEN SENSORS AND OTHER REPAIRS THAT I WAS TOLD WASN'T A PROBLEM BUT I HAD NO OTHER EXPLANATION FOR WHAT HAPPENED. THERE WERE NO CODES THROWN FOR THE MECHANIC TO GO BY. AFTER THE LAST EVENT ON THE HIGHWAY, I TOOK IT TO THE DEALER AND TOLD THEM I WOULD NOT EXCEPT THE TRUCK BACK UNTIL THEY KNEW WHAT IT WAS. AFTER MUCH ARGUING, THEY AGREED TO REPLACE THE CRANKSHAFT POSITION SENSOR UPON MY REQUEST. THEY SAID IT WAS NOT THROWING A CODE FOR THAT AND THEY COULDN'T GUARANTEE IT WOULDN'T BREAK OFF DURING REPAIR AND RESULT IN AN EVEN COSTLIER REPAIR. I DIDN'T CARE AT THAT POINT AND TOLD THEM TO DO IT. I HAD READ MANY OTHER REPORTS ON MECHANIC SITES ABOUT THIS SENSOR BEING RECALLED ON SOME BUT NOT ALL GMC 2500 HD TRUCKS SO I INSISTED THE DEALER REPLACE MINE. MINE DID NOT FALL UNDER THE RECALLED VIN# SO IT WAS OUT OF POCKET FOR ME! IT FIXED THE PROBLEM. I HAVE NOT HAD A PROBLEM SINCE AND IT'S BEEN 2 YEARS NOW. I AM STILL UPSET AT THE LACK OF AGREEMENT ABOUT EXTENDING THE RECALL ON THIS ISSUE TO OTHER VIN#'S. THIS WAS A KNOWN PROBLEM THAT COULD HAVE GOTTEN NOT ONLY ME KILLED, BUT MY 2 YOUNG SONS WHO RIDE WITH ME EVERYWHERE. I AM VERY ANGRY AT THE MAKERS! NOTHING WILL FIX THAT. EVER.

MY WIFE WAS DRIVING WITH OUR 2 KIDS AND THE BRAKE LINE BURST BY THE REAR WHEEL CAUSING THE BRAKES TO FAIL. BRAKES ARE TOO IMPORTANT FOR THIS TO HAPPEN. *JS
VEHICLE DESCRIPTION: CERTAIN PICKUP TRUCKS EQUIPPED WITH 6.6L DIESEL ENGINES FAIL TO COMPLY WITH REQUIREMENTS OF FMVSS NO. 105, "HYDRAULIC AND ELECTRIC BRAKE SYSTEMS." THESE VEHICLES HAVE A BRAKE SYSTEM WARNING LIGHT IN THE INSTRUMENT CLUSTER THAT MAY NOT ILLUMINATE WHEN THE BRAKE FLUID IS LOW. IN ADDITION, WHEN THE BRAKE FLUID IS LOW, THE VEHICLE MAY NOT MEET THE PARTIAL SYSTEM REQUIREMENTS OF FMVSS NO. 105.
Consequence & remedy
Consequence: THESE CONDITIONS COULD RESULT IN REDUCED BRAKING CAPABILITY, WHICH COULD LEAD TO A CRASH.
Remedy: DEALERS WILL CHANGE THE LOCATION OF A WIRE CONNECTION IN THE UNDERHOOD BUSSED ELECTRICAL CENTER. OWNER NOTIFICATION BEGAN JULY 9, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020 OR GMC AT 1-800-462-8782.
VEHICLE DESCRIPTION: CERTAIN 2-WHEEL DRIVE PICKUP TRUCKS FAIL TO COMPLY WITH REQUIREMENTS OF FMVSS NO. 120, "TIRE SELECTION AND RIMS FOR MOTOR VEHICLES OTHER THAN PASSENGER CARS." THE PROBLEM WAS CAUSED BY A COMPUTER ERROR THAT RESULTED IN THE CERTIFICATION LABEL LISTING TIRE SIZE AND INFLATION PRESSURE INFORMATION THAT DIFFER FROM THE TIRE SIZE AND THE INFLATION PRESSURE INFORMATION FOR THE TIRES ON THE VEHICLE. IF THE VEHICLE OWNER OR SOMEONE SERVICING THE VEHICLE INFLATES THE TIRES ACCORDING TO THE PRESSURE SPECIFIED ON THE LABEL VERSUS THE APPROPRIATE PRESSURE FOR THE TIRES, THE TIRES COULD BE UNDER-INFLATED OR OVER-INFLATED DEPENDING ON THE TIRES MOUNTED ON THE VEHICLE.
Consequence & remedy
Consequence: IF THE TIRES ARE UNDER-INFLATED, IT COULD REDUCE THE TREAD LIFE OF THE TIRE, AND THE TIRE COULD DEGRADE TO A POINT OF ALLOWING SUDDEN AIR LOSS. IF THE TIRES ARE OVER-INFLATED, IT COULD REDUCE THE TREAD LIFE OF THE TIRE AND INCREASE SUSCEPTIBILITY TO ROAD HAZARD DAMAGE. IF SUDDEN AIR LOSS OR A ROAD HAZARD CAUSES DAMAGE TO A TIRE, CONTROL OF THE VEHICLE COULD BE ADVERSELY AFFECTED AND COULD RESULT IN A VEHICLE CRASH.
Remedy: OWNERS WILL BE PROVIDED WITH A NEW LABEL AND INSTALLATION INSTRUCTIONS. HOWEVER, A DEALER CAN INSTALL THE LABEL IF THE OWNER SO DESIRES. OWNER NOTIFICATION BEGAN MAY 31, 2001. OWNERS WHO DO NOT RECEIVE THE LABEL AND INSTALLATION INSTRUCTIONS WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020 OR GMC AT 1-800-462-8782.

IN A LETTER DATED NOVEMBER 7, 2007, GENERAL MOTORS (GM) REPORTED TO THE OFFICE OF DEFECTS INVESTIGATION (ODI) THAT IT WILL CONDUCT A SAFETY RECALL (07V-521) TO REPLACE THE CRANK POSITION SENSOR (CKP) IN APPROXIMATELY 12,000 MODEL YEAR (MY) 2001 CHEVROLET SILVERADO AND GMC SIERRA VEHICLES EQUIPPED WITH 8.1 LITER ENGINES MANUFACTURED ON OR BEFORE NOVEMBER 15, 2000.ACCORDING TO GM, THE CKP CAN FAIL INTERMITTENTLY OR PERMANENTLY.A PERMANENT CKP FAILURE WOULD RESULT IN AN ENGINE STALL WITHOUT RESTART.AN INTERMITTENT CKP FAILURE COULD CAUSE THE SERVICE ENGINE SOON LIGHT TO ILLUMINATE, THE VEHICLE TO RUN ROUGH OR THE ENGINE TO STALL BUT ALLOWS RESTART.AS A REMEDY, AN IMPROVED CKP WILL BE INSTALLED IN THE SUBJECT VEHICLES.THE RECALL CAMPAIGN WILL START IN DECEMBER 2007. DURING THE PRELIMINARY EVALUATION (PE06-016), AND THIS EA INVESTIGATION, GM AND ODI INDEPENDENTLY CONDUCTED DETAILED REVIEWS OF CERTAIN FIELD DATA TO UNDERSTAND THE NATURE AND RATE OF SUBJECT VEHICLE STALLING DUE TO CKP FAILURES.GM AND ODI REVIEWED GM'S WARRANTY CLAIMS FOR THE CKP WITH THE OBJECTIVE OF ASCERTAINING AN ESTIMATE OF THOSE CLAIMS REPRESENTING AN ENGINE STALL WHILE DRIVING.THE CKP WARRANTY CLAIMS WITHOUT VERBATIM TEXT WERE THE LARGEST SEGMENT OF WARRANTY CLAIMS.USING THOSE CLAIMS, GM SURVEYED VEHICLE OWNERS TO GATHER ADDITIONAL INFORMATION TO DETERMINE IF THE CLAIM WAS ASSOCIATED WITH A STALL WHILE DRIVING EVENT.BASED ON THE SURVEY, GM ESTIMATED THAT APPROXIMATELY 49% OF ALL WARRANTY REPAIRS FOR THE CKP INVOLVED A STALL WHILE DRIVING.ODI?S REVIEW OF GM'S SURVEY DATA PRODUCED A HIGHER ESTIMATE (71%) FOR STALL WHILE DRIVING.GM FURTHER ESTIMATED THE RATE OF STALL WHILE DRIVING FOR THE SUBJECT VEHICLES OVER TIME.IT ESTIMATED STALLING WHILE DRIVING RATES OF 1.6%, 4.6% AND 8.9% AT 1, 3 AND 6 YEARS IN SERVICE RESPECTIVELY.ODI'S REVIEW OF THE GM'S SURVEY DATA FINDS HIGHER ESTIMATED STALL WHILE DRIVING RATES OF 2.2%, 6.8% AND 13% AT 1, 3 AND 6 YEARS IN SERVICE RESPECTIVELY. ODI ALSO CONDUCTED A SURVEY OF VEHICLE OWNERS USING CONSUMER COMPLAINTS REPORTED TO BOTH ODI AND GM.THE OBJECTIVE WAS TO ASCERTAIN THE POTENTIAL SAFETY CONSEQUENCES OF AN ENGINE STALL DUE TO THE ALLEGED DEFECT.WITH RESPECT TO THE ABILITY TO RESTART THE VEHICLE AFTER A STALL, 11% REPORTED IMMEDIATE RESTART, 69% REPORTED DELAYED RESTART AND 20% REPORTED NO RESTART.OVER HALF NOTED AT LEAST ONE ENGINE STALL INCIDENT AT SPEEDS IN EXCESS OF 40MPH. ABOUT ONE-THIRD NOTED THE VEHICLE WAS STRANDED EITHER PARTIALLY OR FULLY IN A LANE OF TRAFFIC AFTER THE ENGINE STALL.ALL OF THE CONSUMERS SURVEYED NOTED MULTIPLE STALLING EVENTS PRIOR TO PROPER DIAGNOSIS AND REPLACEMENT OF THE CKP.BASED ON GM'S DECISION TO CONDUCT A SAFETY RECALL, THIS INVESTIGATION IS CLOSED.
